Bending involves the deformation of a metal sheet along a straight axis, resulting in angular changes and the creation of U-shapes, V-shapes, and other bend configurations.


Stretch forming elongates the metal sheet over a die, increasing its surface area without thinning the material, making it suitable for producing curved or contoured parts.

Deep Drawing

Deep drawing transforms a flat sheet metal blank into a hollow shape through the use of a punch and die, commonly utilized in the production of cans, enclosures, and automotive components.

Roll Forming

Roll forming utilizes a series of continuous bending operations to progressively shape the metal sheet into the desired profile, making it ideal for producing long lengths of consistent cross-sectional profiles.

Superplastic Forming

Superplastic forming enables the shaping of intricate and lightweight components by heating the metal sheet to a specific temperature range, allowing for high elongation and complex geometries.
